Work: Calculate the value of equation 180+arctan(13.1/(-5.7))+arctan(13.1/(5-5.7))+arctan(13.1/(20-5.7)) .
Question type: Mathematical calculation
Solution:
180+arctan(13.1/(-5.7))+arctan(13.1/(5-5.7))+arctan(13.1/(20-5.7))
=180+arctan(13.1/(-5.7))+arctan(13.1/(5-5.7))+arctan(13.1/(20-5.7))
=180+arctan(-2.298246)+arctan(13.1/(5-5.7))+arctan(13.1/(20-5.7))
=180+arctan-2.298246+arctan(13.1/(-0.7))+arctan(13.1/(20-5.7))
=180+arctan-2.298246+arctan(-18.714286)+arctan(13.1/(20-5.7))
=180+arctan-2.298246+arctan-18.714286+arctan(13.1/14.3)
=180+arctan-2.298246+arctan-18.714286+arctan0.916084
=180+-1.16039+arctan-18.714286+arctan0.916084
=180+-1.16039+-1.517412+arctan0.916084
=180+-1.16039+-1.517412+0.741631
=178.83961+(-1.517412)+0.741631
=177.322198+0.741631
=178.063829
Answer:180+arctan(13.1/(-5.7))+arctan(13.1/(5-5.7))+arctan(13.1/(20-5.7))=178.063829
